AO10
TCO COATED GLASS FOR THIN FILM APPLICATION (a-Si)
AO10 is a clear float glass, coated with Transparent Conductive Oxide
(TCO). The right balance between transmission, haze and conductibility
of the TCO coating enables for improving the thin film cell efficiency.
Indeed, when rightly deposited, the TCO has the potential
• to lower the reflection at the interface with the absorber;
• to increase the path of light into the absorber;
• to trap the light into the absorber.
Combined with the excellent durability of glass, AO10 is the product of
choice for thin film photovoltaic modules (amorphous silicon).
AO10 conforms to EN572 and is fully temperable.
